One more thing what's the distance between two consecutive Earth Pit what's the exact standard if you can please explain this the the minimum distance between two consecutive Earth pits

Hello, this is Kyoritsu Japan. It is so honor that you used our product. We highly trust we can learn more from your excellence in feedback on electrical equipment. If you don't mind, we can contact via email.
Great You from Kyoritsu Company Right
Thanks again
Please could you explain the operation of the meter and the readings.
whats the meaning of 20ohms, 200ohms, and 2000ohms ?
Earth Impedance/resistance. 20ohms is the range of that particular selection of the meter. If there is no reading in that range, we need to find it in the next range which is 200ohm range, and if still no reading needs to step up to the next range which is 2000ohm. Earth Impedance/resistance depends on the regulations of the country. For example my country only allows under 50ohm for residential areas, under 10ohm for public areas and under 1ohm for substation/transformers/high sensitivity industrial equipment.
It was beneficial
dapat macam mana formula untuk 1/2"
good
What about the grounding rod resistance?each rod shall be tested and removed all connected cable before the test of total resistance grounding.
Not really it depends on the situation and regulations of the country. We usually do it at the installation state, we check each time the rod is inserted to the earth. These guys in the video are doing inspection for application form.
Good interesting vedio😊😊😊
Why the leads are in same line? pliz assist me sir.
Are you dumb?
Terima Kasi baru Tau saya
I had an exams question in college how to do earth rod test . I didn’t pass it 😢
when lightning strikes the earth doesn't the surge enter the house via the earth wiring? If so isn't it dangerous, probably better not to have any earthing system at all?
Why is the leads in the same line
Rather hear an explanation
What readings should tell me that the resistance is not okay please
depend on local regulation ..as lower as possible. .below 10ohm
music is shocking
Good job bro

Test ini apakah harus saat listrik off?
Kalau tak ada bocor ke bumi tak perlu off. Sebab tu dia check voltage dulu.

Why to use this device with long cables and sticks while THEORETICALLY one can get more relevant results using any household electric appliance like, say, Incandescent light bulb, a mulimeter and the old good Ohm's Law? One terminal of the bulb is connected to live (hot), the other to earth and the current is measured. Divide voltage by current and subtruct the bulb's resistance and the result is the earth resistance. What is wrong in such approach?
The results would only be resistance on the load , not main earth resistance
@@Godfa539 will you justify this statement please?
I get what you mean and yes you can get accurate measurement through ohms wall but use a proper load resistor that is large enough to limit the current so the damage you will cause on the ground rod is limited.
For regulations and way safer than dealing with life voltage. This device can measure the actual earthing rod resistance accurately in a +-40 square meter to the next transformer's earthing rod.
Sir, how 1). If earth got voltage, what is the next action.. 2). When to use the setting mode 200 & 2000? Apprecite ur answer
អរគុណThank
Black wire for nuetral. Nice
Does it mean now the earth resistance is perfect?
The video I was looking for! Excellent explanation of the test. Thank you so much! Ps: The background music is pleasant and appropriate!
Good job..🎉 im practical test
❤
Is Photocel's resistance value a concern ?
13A..enough for lighting circuit
You demonstrate this critical task to look easily, Thank you very much a learn a lot through your video.
Good country with laws and people that know a well earth ground safe tere life, reduce EMC, lower the body contact voltage, ... Wow well electrician = You controlled (only optical) the ground connection boxes around the house. For the beginning well done. I hope you measure the low resistance later to be sure that the connections are not corroded. Fine work und knowledge ! Well done. Attention your result is influence of the premium earth groundind metal in the earth. Keep the measuring line far away or you get worse results. 2.10 Ohm is very very low = perfect but in my country I start thinking why is it so low ? Where is the fault to get these brilliant results ? Very wet earth ? Under the measuring line = really no water pips, no powerlines, no other pipes/metallsheets , ... What is hidden under the bid concret by the 2nd Spike movement. Testing the earth voltage = well done you know the users manual ! Perfect We use different instruments in europe (english version form page 37 to page 72) www.dehn.de/store/f/27628622/EBA/1805_060583_GEOHM_Messger%C3%A4t.pdf And other brands. My thumb up for your video.
Tutorial worked a treat😊
video excelente parabens , abraços do Brasil .
Thanls for sharingbthis video. It helps me a lots
Is there a specific number of times that earth resistance testing should be done for a specific area? (like number of times per meter squard)
Ese método no existe, tomaste medidas arbitrarias y sacaste un promedio... No tiene sentido.
Attack of the silent explanation vid strikes yet again
Hahaha..Mr bean vers 2
Sir the result you shown is that good or bad grounding
Good ..under 10 ohm
Thanks sir......
Thank you for the effort made in the video.... I have a question... Is it true that the yellow wire is supposed to be an extension of the red wire, meaning on one line to give the reading... Why change in yellow only and should it be changed in red? ??
To individually test the earth rod disconnect tape from earth rod
❤
Thank you Engineer
Good, Thanks
if we had no access to such equipment will adding more grounding rods to the ground all connected together potentially reduce the earth resistance?
Yes.
@@rictorrictor888 🐱👍🏿
thanks :)
Shifting potential spike in perpendicular ( left and right)direction is not correct.
Appreciate 👌👌you have done share gr8 experience with kyoritsu instrument 💐 This is sanjeev raghav from kyoritsu
Thank too .kyoritsu always the great equipment ..
This method is not FOP.
